Yes, ill be doing BG restores. Not all are saveable though.
Secret is to use translucent paint and to do all work over a lightbox so you can see your imperfections immediately and rectify. Colour matching needs to be done on a seperate sheet of glass.
But badly flaking Bg's really are too far gone. Those with weak colours or particular colours that have disappeared ( thinking RED on Flash here) can be brought back to new condition as can scratches etc.
This service WILL be available soon - from new year onwards.
I need to post results i have here first
